Relating length measurements to addition and subtraction
Key terms:
Height, difference, sum
Prerequisite knowledge:
Addition of single digit numbers to more three-digit numbers.
A brief description of the "hook" or activity:
Start by dividing students up into groups of about 4 or 5, and within each group to line up all the students in height order. They will measure the smallest person in the group using centimeters. Then, they will measure and record the height differences between every two consecutive persons (shortest to second shortest; second shortest to third shortest; etc). In the end, they will use the collected data to predict how tall the tallest person is from their group. They will then actually measure that person to see if their predictions were accurate.

Notes on using this lesson / suggested assessment / etc:
As an assessment, you can tell the students in the end how tall you are, and ask them to try to figure out how much taller you are than them. For homework, they can go home and measure their family's heights to find out how much taller / shorter their family members are than them.
